Undervoltage Error

What does 02 mean?

The power circuit board has detected an undervoltage condition in the input power supply. This can lead to improper operation, instability, or failure of the system's components, particularly the compressor, due to insufficient power.

• Input voltage to the unit is below the normal operating range.
• Voltage sag or brownout from the electrical grid.
• Faulty power supply.
• Loose electrical connections.

Click steps to track your progress.

1. 1

   Measure the input power supply voltage at the main terminals to verify the actual voltage level.

2. 2

   Check the external power supply for stability and correct voltage output.

3. 3

   Inspect the power circuit board for any visible damage or component failure.
